BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a refrigerator with condensation-preventing air guides, and more particularly, to a condensation preventing arrangement for preventing formation of condensation on a cover of an intermediate partition of a side-by-side refrigerator.

2. Description of Related Art

Recently, side-by-side refrigerators having storage compartments defined in a main body and arranged in a side by side relationship in the main body have been actively developed, as the refrigerators are high-grade and large-sized.

Generally, a side-by-side refrigerator includes a cabinet having storage compartments defined therein and divided by means of an intermediate partition in such a manner that the storage compartments are arranged side by side. The cabinet forms an outer main body of the refrigerator. The left and right doors are hinged to the front part of the cabinet for closing the storage compartments. The intermediate partition includes a heat-insulation wall, which is formed of foamed urethane, and left and right inner members provided at both sides of the heat-insulation wall. The storage compartments are divided into left and right storage compartments by the left and right inner members. To the front part of the intermediate partition is attached a cover, which is made of steel. The front ends of the left and right inner members are fixed to each other while being sealed by the cover. When the left and right doors are closed, gaskets tightly contact the cover. The outer surface of the cover is exposed to the outside. Consequently, condensation is formed on the cover when low-temperature air in the storage compartments is transmitted to the cover during the operation of the refrigerator. Condensation is undesirable as it is both a potential maintenance and health issue. The condensation spots the cover or runs down to the floor of a kitchen where the refrigerator is installed, whereby the kitchen becomes unsanitary.

One known solution to this problem is to lay a hot pipe connected to a condenser of a refrigerating cycle at the rear part of the cover so that heat from the hot pipe is discharged to the cover, and thus formation of condensation on the cover is prevented. Such an arrangement is disclosed in Korean Unexamined Patent Publication No. 2001-0019305 and U.S. Pat. No. 6,666,043.

In a refrigerator with the aforementioned arrangement, however, the hot pipe may be broken when foaming liquid is injected after the hot pipe is placed at the rear part of the cover. Also, the foaming liquid may be excessively injected between the hot pipe and the cover with the result that radiation of the heat is not properly accomplished. Furthermore, the cost and time for constructing the hot pipe are increased since the hot pipe is necessary.

Consequently, the other door 300 or 200 is not affected by the opened or closed door 200 or 300 although the end parts 232 and 332 of the left and right air guides 230 and 330 partially overlap each other.

The operation of a refrigerator according to the present embodiment of the present invention will be hereinafter described.

The refrigerator serves to cool food stored in the storage compartments 120 and 130 by a refrigerating device including the compressor 141 and the condenser 142.

In the refrigerator, the compressor 141 and the condenser 142 are mounted in the machine compartment 140 disposed at the lower rear part of the cabinet 100. Since the condenser 142 is not exposed to the outside, it is necessary to circulate air around the condenser 142 to cool the condenser 142. To this end, the operation of the blowing fan 143 is required. When the blowing fan 143 is operated during the operation of the refrigerator, indoor air is introduced into the machine compartment 140 through the inlet duct 144. The introduced air is circulated around the condenser 142 and the compressor 141 so that the condenser 142 and the compressor 141 are cooled by the circulated air.

The air having a high temperature by heat exchange with the compressor 141 and condenser 142 is discharged through the outlet duct 145. The discharged air is guided between the left and right doors 200 and 300 in front of the cover 114 of the intermediate partition 110 by the outlet duct 145. In front of the cover, the hermetically sealed channel is formed by the left and right air guides 230 and 330. Consequently, the high-temperature air moves to the storage compartments along the hermetically sealed channel.

When the high-temperature air flows along the hermetically sealed channel, heat is exchanged between the high-temperature air and the surrounding members forming the hermetically sealed channel. As a result, the temperature of the cover 114 of the intermediate partition 110 is increased, which is accomplished by the conventional hot pipe serving to increase the temperature of the cover 114. Consequently, formation of condensation on the cover is prevented.

The air guides 230 and 330 serve to prevent contact between the indoor air and the cover 114 in addition to the above-mentioned functions. Consequently, the effect of preventing formation of condensation is improved. When the condensation is formed on the cover, the hot air discharged from the machine compartment is continuously blown to the cover, whereby the condensation formed on the cover is quickly evaporated.

A refrigerator according to the present embodiment has air guides for guiding air discharged from a machine compartment so that it passes by the front of a cover of an intermediate partition. Consequently, formation of condensation on the cover is prevented without providing the conventional hot pipe. Furthermore, the cost and time for mounting the conventional hot pipe are decreased since the hot pipe is not necessary.
